Description

Technical Field

[0001] This utility model relates to the field of winding mechanism technology, and in particular to a winding mechanism for hybrid fiber composite fabric. Background Technology

[0002] With the rapid development of the textile industry, composite fiber fabrics have been widely used in aerospace, automotive interiors, protective clothing, and high-performance filtration materials due to their excellent physical properties and multifunctionality. Hybrid fiber composite fabrics are made by combining various types of fibers through specific processes, possessing superior mechanical properties, thermal stability, and functionality compared to single-fiber fabrics. However, due to their complex structure, uneven surface friction coefficient, and significant thickness variations, defects such as wrinkles, uneven tension, and edge warping are prone to occur during subsequent processing, especially in the winding stage, severely affecting product quality and subsequent application performance.

[0003] Currently, traditional fabric winding mechanisms mostly employ fixed guide rollers combined with constant tension control, which is insufficient to adapt to the dynamic changes in the performance of hybrid fiber composite fabrics during operation. Existing technologies lack tension adjustment mechanisms, making effective tension control of localized areas of the composite fabric impossible. Furthermore, existing technologies lack zoning devices, resulting in a lack of flexible dynamic zoning capabilities. This causes the fabric to easily slide to different zones after cutting, leading to friction and affecting product quality. Therefore, there is an urgent need for a winding mechanism capable of achieving precise zoning control and adaptive tension adjustment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hybrid fiber composite fabric winding mechanism, including a frame, a motor fixedly connected to the frame, a winding rod driven by the motor, a partitioning device on the upper part of the winding rod, a guide roller rotatably connected to the frame, a tension adjusting device on the upper part of the guide roller, the partitioning device including a first fixed plate, a hydraulic cylinder mounted on the first fixed plate, an adjusting rod fixedly connected to the lower part of the piston rod of the hydraulic cylinder, a first fixed shaft fixedly connected to the lower part of the adjusting rod, a partitioning plate slidably connected to the first fixed shaft, and a notch provided on the partitioning plate.

[0005] The adjusting rod has several screw holes, and the upper part of the partition plate is fixedly connected to a connecting lug. The connecting lug is connected to the adjusting rod by bolts, and end plates are welded to the adjusting rod and the first fixed shaft.

[0006] The tension adjusting device includes a second fixed shaft, on which a sleeve is fixedly connected, and a sliding groove is fixedly connected to the lower part of the sleeve.

[0007] The slide groove is slidably connected to a slider, the lower part of the slider is provided with a spring, and a third fixed shaft is fixedly connected to the slider.

[0008] A wheel is mounted on the third fixed shaft, and an adjusting bolt is threadedly connected to the second fixed shaft.

[0009] An ion air knife is fixedly connected to the frame, and an air expansion shaft is rotatably connected to the frame.

[0010] Compared with existing technologies, the advantages of this invention are as follows: This winding mechanism, by incorporating a partitioning device including a hydraulic cylinder, adjusting rod, first fixed shaft, partitioning plate, and connecting ears, can flexibly adjust the spacing between partitions according to the fabric width and segmentation requirements, and achieve dynamic adjustment in the height direction through hydraulic drive. The partitioning plate has a notch at the bottom to effectively avoid fabric edges and prevent surface scratches. This partitioning structure forms clear physical isolation zones during fabric movement and winding, preventing displacement, overlap, or mutual friction between adjacent areas, thereby significantly improving fabric quality and winding neatness.

[0011] Secondly, the tension adjustment device consists of a second fixed shaft, a slide groove, a slider, a spring, a third fixed shaft, wheels, and adjusting bolts. It can adaptively compensate for tension fluctuations during fabric movement. When localized tension changes occur due to uneven fabric thickness or material differences, the slider can slide up and down within the slide groove, absorbing excess stress through the elastic deformation of the spring, thereby maintaining the stability of the fabric tension. Simultaneously, the adjusting bolts allow for fine-tuning of the slider's initial position, setting reference tension values ​​for different working conditions, thus improving the equipment's applicability and control accuracy.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-5 The illustrated hybrid fiber composite fabric winding mechanism includes a frame 1, a motor 2 fixedly connected to the frame 1, a winding rod 4 driven by the motor 2, a partitioning device 3 on the upper part of the winding rod 4, the partitioning device 3 including a first fixed plate 32, a hydraulic cylinder 31 mounted on the first fixed plate 32, an adjusting rod 33 fixedly connected to the lower part of the piston rod of the hydraulic cylinder 31, a first fixed shaft 34 fixedly connected to the lower part of the adjusting rod 33, a partitioning plate 36 slidably connected to the first fixed shaft 34, and a notch 37 provided on the partitioning plate 36. The adjusting rod 33 has several screw holes, a connecting lug 38 fixedly connected to the upper part of the partitioning plate 36, the connecting lug 38 being connected to the adjusting rod 33 by bolts, and an end plate 35 welded to the adjusting rod 33 and the first fixed shaft 34.

[0021] A guide roller 5 is rotatably connected to the frame 1. A tension adjusting device 8 is located on the upper part of the guide roller 5. The tension adjusting device 8 includes a second fixed shaft 81, a sleeve 86 fixedly connected to the second fixed shaft 81, and a slide groove 85 fixedly connected to the lower part of the sleeve 86. A slider 87 is slidably connected inside the slide groove 85. A spring 88 is located at the lower part of the slider 87, and a third fixed shaft 84 is fixedly connected to the slider 87. A wheel 83 is mounted on the third fixed shaft 84, and an adjusting bolt 82 is threadedly connected to the second fixed shaft 81.

[0022] An ion air knife 6 is fixedly connected to the frame 1, and an air shaft 7 is rotatably connected to the frame 1.

[0023] The ion air knife 6 is a crucial component in this invention for eliminating static electricity generated by friction during fabric winding. Its working principle is based on ionization technology. A high-voltage generator produces a high voltage, ionizing oxygen and nitrogen molecules in the air to generate positive and negative ions. These ions are then carried by a high-speed airflow and evenly blown onto the fabric surface. When the statically charged fabric passes through the ion air knife 6, the static charge on its surface combines with the oppositely charged ions in the airflow, thus achieving static neutralization. This design not only effectively reduces static electricity accumulation on the fabric surface, preventing the mutual adsorption between fabric particles and the adhesion of dust particles, but also avoids phenomena such as pilling and knotting caused by static electricity, ensuring smooth fabric operation and high-quality winding.

[0024] The air shaft 7, as a key component in this invention for improving the fit between the fabric and the winding rod 4, primarily functions to enhance the tightness and flatness of the fabric during the winding process. The air shaft 7 contains one or more air chambers. When air is injected into the air chambers through an external air source, the chambers expand, increasing the outer diameter of the shaft and causing the fabric mounted on it to adhere tightly to the surface of the air shaft 7. This mechanism not only improves the stability of the fabric during the winding process but also effectively prevents fabric slippage and loosening, ensuring the finished winding product has good neatness and compactness.

[0025] Working Principle: During operation, motor 2 drives the winding rod 4 to rotate, causing the fabric to continuously wind up along a set path. To adapt to tension fluctuations caused by uneven thickness and material differences in the mixed fiber composite fabric, a tension adjustment device 8 is installed on the frame 1. Its core structure includes a second fixed shaft 81, on which a sleeve 86 is fixedly connected. A slide groove 85 is fixedly connected to the lower part of the sleeve 86. A slider 87 is slidably connected inside the slide groove 85. A spring 88 is provided at the lower part of the slider 87. A third fixed shaft 84 is fixedly connected to the slider 87, on which a wheel 83 is installed. An adjusting bolt 82 is threadedly connected to the second fixed shaft 81. When the fabric floats up and down due to local tension changes during operation, the slider 87 slides up and down within the slide groove 85, and the elastic deformation of the spring 88 absorbs the tension fluctuations, achieving adaptive compensation for the tension during fabric operation. Meanwhile, the initial position of the slider 87 can be finely adjusted by adjusting bolt 82, thereby setting the reference tension value under different working conditions and improving the applicability and control accuracy of the equipment.

[0026] Furthermore, to prevent damage caused by lateral displacement or slippage after cutting during the fabric winding process due to mutual friction, this invention specifically includes a partitioning device 3, which mainly comprises a hydraulic cylinder 31. An adjusting rod 33 is fixedly connected to the lower part of the piston rod of the hydraulic cylinder 31. A first fixed shaft 34 is fixedly connected to the lower part of the adjusting rod 33. A partitioning plate 36 is slidably connected to the first fixed shaft 34, and the partitioning plate 36 has a notch 37. Several screw holes are provided on the adjusting rod 33. A connecting ear 38 is fixedly connected to the upper part of the partitioning plate 36, and the connecting ear 38 is connected to the adjusting rod 33 by bolts. End plates 35 are welded to the adjusting rod 33 and the first fixed shaft 34. The hydraulic cylinder 31 drives the adjusting rod 33 to move up and down through the piston rod, thereby adjusting the height of the partitioning plate 36. The partitioning plate 36 is bolted to the adjusting rod 33 via the connecting ear 38, facilitating flexible adjustment of the partition spacing according to the actual fabric width and segmentation requirements. The partitioning plate 36 has a notch 37 at its bottom to avoid scratches on the fabric edges. This partitioned structure can form a clear physical isolation zone during the fabric's movement, preventing displacement, overlap, or friction between adjacent areas, and significantly improving fabric quality and roll-up neatness.

[0027] Furthermore, to address issues such as fabric adhesion and pilling caused by static electricity accumulation during the winding process, this invention also includes an ion air knife 6 fixedly connected to the frame 1. This ion air knife neutralizes the surface charge of the fabric, reduces static interference, and ensures smooth fabric movement. An air shaft 7 is rotatably connected to the frame 1 to enhance the adhesion between the fabric and the winding roller during the winding process, ensuring that the fabric is evenly and tightly wound onto the winding rod 4.

[0028] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
